linux下mysql安装

[hopen]

我用的是源码编译方式安装的，mysql能够安装完后，不能启动服务。提示错误

mysql低版本安装后不会自动启动服务的,所有要手工启动服务,然后在mysql进去
如果是4.0或以上版本应该安装完后自动启动服务器了,在命令行mysql就可以进去了,
建议用rpm方式安装,然后确定下系统mysql安装是否成功(有的系统在安装的时候已经装的有低版本的,这时的强制安装才行)

是用ROOT启动的吗?
#/etc/init.d/mysqld start

这次晕倒了，不是别的问题，是磁盘空间不够了。不知谁安装的机器，近80G的硬盘
/home分了70，其余的分了5G

谢谢二位了，结贴！
